Benefits
Because you can maintain and upgrade the program in the MN102HF75K/85K
up to and immediately following product release, this version of the device
shortens time-to-market by as much as one month. This device is ideal for appli-
shortens time-to-market by as much as one month. This device is ideal for appli-
cations in quickly changing markets, since it allows you to revise the microcon-
troller program in an existing product.

Using the PROM Writer Mode
In this mode, the MN102HF75K allows a PROM writer to program the internal
flash memory as if it was a standalone memory chip. The microcontroller is
flash memory as if it was a standalone memory chip. The microcontroller is
inserted into a dedicated adaptor socket, which connects to DATA-I/O’s LabSite
PROM writer. When the microcontroller connects to the adaptor socket, it auto-
PROM writer. When the microcontroller connects to the adaptor socket, it auto-
matically enters PROM writer mode. The adaptor socket ties the microcontroller
pin states to PROM writer mode, and programming occurs without any reference
pin states to PROM writer mode, and programming occurs without any reference
to the microcontroller pin states.
